A firearm question for you Lefties

Handguns have to be revolvers, rifles have to be bolt- or lever-action, shotguns have to be pumped.

Like the .44 Magnum, or the M40, and pump action shotguns tend to not have trigger disconnectors, so accidental (and rapid) discharge there. Granted, none of my examples are hundred year old, but I think the overall point that they're not any less lethal than modern tech is still valid.

Just to add, I prefer revolvers and bolt action rifles for the very reason that they're much more reliable weapons.

Well sure, add whatever trigger disconnectors or safeties modern technology affords. I'm no expert. My only intent was to slow down the rate of fire.

And of course, slowing the rate of fire is an action to mitigate mass shootings, when as I've stated before, the bigger problem is the thousands of "mundane" shootings. And many mundane shootings would be as deadly with a six-shooter as with an uzi, but it will still mitigate those to some degree as well. Harder to hit a bystander with a stray bullet in a gang shooting when there's less bullets flying around.
